Booirrn ail-British subject, residing at Shirley House, Main Road,Sidcup, Kent England have invented certain new and uselul ImprovementsinTypographic Composin 'iv achines and I do herebydeclare the following tobe a i ull clear and exact descri ation of thesame, reference being hadtothe accompanying drawings, forming part this specification, and to thecharacters of reference marked thereon.

This invention relates to keyboard machines for composing o'r preparingrecord strips, patterns orcontrollers which are Gillplayed tocontrolthe' actionbi automatic type casting and composing machines Thekeyboard composing machine to which 7 this invention particularlyrelates is shown in part in the accompanying"drawings and is of theclass of machines Well known comnieircially as the product of LanstonMonotype lilachine Company and disclosed as to eral featuresinUnitedStates Letters i nt Noi9 i n i dated December 28, 1909. These machinesare well known to those skilled thea'rt so that a detailed descriptionof UIGlI'CODStFLlCtlQIl and operation is not deemed necessary herein.The keys Whenoperated 'are'ada qted to produce sigrials-in theiorm' oiperforations in'a record strip ot paper or the" like,'which signalsusually each comprise two perforations representing a unit, character,symbol or justification fraction. The signal producingdevices include aseries of punches which by their location coincide With the componentsof the signal pertaining to the oper- Certain of these punchcs areconnected with a series of stop bars through Which the movement of thepunches is communicated to a series of stops torming'part of the'unitsmeasuring mechanism and each denoting different unit'value. The unitsmeasuring mechanism registers the value of each signal in a well knownmanner to aid in ascertaining the justification fraction or theappropriate signal or signals therefor to complete each line ofcomposition.

In the general organization ofthe machine the fraction or unitsnecessary to justify a 'linearc addedto a certain predetermined spacebody size which is variable setwise as distinguishedirom type bodieswith control Of this signal.

predetermined or fixed unit values or diinensions, such as characters,points, quads, and the like. it has, however, been proposed for examplein United States Letters Patent 1,09 l,630 dated April 28, 191 i,1,283,958 dated llOVGlIlbQI' 5, 1918, 1,807,718 dated June 2%, 1919 and1,307,719 dated June 1919, to provide mechanism whereby thejustification fractioncan be applied to the normal non-justifiable orfixed dimension type bodies.

may also he poii'ited out that in keyboard machines of this class onecomponent of the usual signal indicates position and the other componentdimension and position because while the first component indicates a dieor matrix position in the casting machine in which the controller is tohe used. the second component not only indicates matrix position butalso determines and controls the positioning of the normal molddimensioning;- mechanism for the selected matrix. This second componentis produced by a signal producing member which is coupled with aselected one of the stop bars and stops as previously mentioned so thatthe line measuring mechanism will record the unit alue oi? the signaltocorrespond with the unit value of the type bodv produced under Thesesignal components will be referred to hereinafter as the position anddimensioning components pectively.

When space key or space bar is struck between Words it produces a signalthe dincnsioning component oi. which controls in she castingmachine theposition of the normal mold dimensioning mechanism as Well as the matrixposition for castingthe space: the other component of a spacesignal controls the transier mechanism which effects change in the value oi? thenormal mold ensioning mechanism by combiningit with the supplementary orjustification mold dimensioning mechanism. Thus, the space signalproduces in the casting machine a bod the dimension of which iscontrolled not only by the normal mold dimensioning inech m placed inposition by the dimen- 4 component of the space signal, nut also by thejustiiication mold dimensioninq mechanism. the latter having been ccd inposition by the previous. justification 519: nal in the controller. Thepunch in the composing machine for producing the transfer component ofthe space signal is normally connected with a stop bar and stop toregister the unit value of the justified space at a fixed amount,usually four units.

With the above mentioned mechanism the dimension indicated for any givenposition of the normal mold dimensioning devices is tWo units less whencontrolled by the dimensioning component of a space signal than whencontrolled by the like component of a type signal. (lo-operating withthe mechanism for setting the justification inclicatiug mechanism inaccordance with the line remainder is a space number indicator which-isoperated each time a justification space is recorded.

The principal objects of the present invention are to provide mechanism,capable o1 being applied to machines in use, for connecting the tra sfersignal producing mechanism with a selected stop bar and stop of theunits measuring mechanism whereby there may be produced a larger minimumjustifiable space than and in addition to the usual or normal four unitsabove referred to, and the justification fraction may be added to typebodies. These objects Wlll. be more particularly explained hereinafterand other objects and advantages will be pointed out or will otherwiseappear in connection with the following description of the device shownin the accompanying drawings and embodying the present invention, inwhich drawings,

As a part -of the organization of .the

bars 1, (Fig. 'Sj with theirpunches 1 and the universal bar 1: thosepunches which produce dimensioning components of sig nals areconnected'by means of the levers 3 pivoted on the arise, theirendscresting in sockets 2 in the punch bars, with the stops 5 throughthe medium of the stop bars 6, the casing or frame for which stop barsis indicated by the characteri: the stops are pivoted on the axis 8 andare adapted to be raised before the pin 9 of the-stop rack '10simultaneously with the operation of the punch connected with the raisedstop. The

stop bar unit 7 is a familiar part of the well known machlne and is madeso as to be removable and replaceable.

According to the present invention the 7 with a vertically slidingmember 16 having a socket 17 for the reception of the. lever 3 andarranged to siide within the frame 7. This member 16 is rigidlyconnected with a horizontal bar 12 also arranged to slide verticallyandthis bar is provided with a member 11 mounted thereon to slide in ahorizontal direction. This member 11 is provided with projections 14 and15, (Fig. 7)

which projections can be brought over the upper ends of different barsin the series 6 as desired. In the normal position'of the member 11 inwhich the basic value of the space is to be. registered as four units,as shown in Fig. 2, the projection 143is above the extended upper end ofstop bar 18 e011- nected with the four unit stop of the series of stopsInthe abnormal position of the member 11, (shown in F at) the projection15 is above the extended upper end of bar 22 connected with the sevenuni stop. The bar 18 is returned to its initial position by a. sprin 19,one end of which is secured-to a lug 20 on the bar;18 and the other endto a stud 21 on theframe 7 (see Figs. 1, 3 and 7). The bar 22 has ashoulder 23 similar to the shoulder .23 shown in Fig- 8 upon which oneof the levers 3 bears and this bar is'returned to 7'0 1 patentedkeyboard eomp'osing machine illustrated there will be recognized thepunch initial position by a' spring 24 similar to the spring-'19.

When the space key'25 (shownin Figs: 10 and 11), is desiredto bQ'HSQClinconnection with normal spacing it may be constructed so as to besupported on a rod 6 by two levers 27 supporting at-their lower ends=aplate 28 on which is mounted a sliding plate 29 having a lug 30 toengage with thekey bar 32 to operate in the usual fashion a punch forproducing a signal component indicating the six unit position of thematrix case. It will be understood"thatwiththis adjustment of thesliding plate-'29 there-isa corresponding adjustment of the member 11 sothat (as shown in FigQQ), the operation of the S punch producing thetransfer component of the signal will causethe operation of the fourunit stop. In other words, the combined signal will measure four unitsbut will place the matrixcase and normal mold dimensioning mechanism insix unitposition, it being remembered that'the transfer component of thesignal will cause the casting machine to cast a type or space body bymeans of the combination oi the normal and the justification molddimensioning mechanism and that when this'combination is used the castis two units less than would normally be recordedby the keyboard.

The slide plate 29 is also provided with a lug 31 so that whenadjustedfrom thenormal dotted position of Fig. 11 to the abnormal full lineposition it will operate valve bar 33 to produce a signal componentindicating the nine unit position of the matrix case. lVith' thisadjustment ofthe' plate 29 the member 11 will be adjusted as shown inFig. & andwill couple the S punch through the members '16, 11 aud'12with the bar 22 and the seven" unit stop of the series of stops 5.

A member 13 in the'form or" a plate is mounted in the frame 7 so that-it can'be vertically reciprocated by the coupling bars 6 pertaining totypeor charactersignals. It is adapted to be coupled withpl ate 111 andbar 12' when justificationis to be added to type signals and for thispurpose itis provided. with a hook 3 1 (Fig. 6) whichis turnished withslot or. groove 35 .into which the lug 36 on theplate 13 enters. Thehook 34 passes up through a slot 37 in the underside or plate 11' and isin position to be engaged by the shoulder 38 on the plate 11 when thelatter is moved tothe "position, (see Figs. 5 and'G), which it assumeswhen the transfer component is to be added to type signals.

In this position of the plate 11 the projections 14 and 15 thereon donot engage any of the bars 6. The bars 6 pertaining to type signals havea shoulder 4E0 (see Fig 8) which projects over the upper "side of theplate 13 so that when any one of these bars ismoved downward on -theoperation of a type or character key such bar carries with it-the plate13 andthis plate through its hook- 3etpullsthe members 11 and 12downward so that the punch representing the transfer component of thespace si nal is operated through the partlfi and its lever and itssignal is added to each type signal. In'Figso-"and "6 the Y mechanism isshown in theposition assumeda'ftera type signal to which thejustificationis to be added has been produced by the depression 01? atype key.

To facilitate the adjustment of the plate 11 along the-barQQ-thereisprovid'ed on the outside of the frame 7 a sliding finger or thumb*piece'39, (Figs. 1, 3, land 8) connected with a block 41 slidablymounted in a slot 12 in the 'liront plate of the frame 7.

Attached to the hlo'cl ll is a rib t3 which rests in'a groove 14 in theplate 11 (Figs. 6 and'-7).- Cooperating with the finger piece 39*isaspringcatch 15 adapted to engage with slots in the edge of-the thumbpiece at each" position of adjustment of the plate (Fig. 1). Vi

Tominimizethe danger of damage to the parts and to prevent inaccurateadjustment of the plate 11; provision is made so that the adjustmentcan-'onlybemade when the stop bars are in -initial position. Forthisp'.irpose there is mounted in the top plate 46 of the frame 7ablocln 17 (Fig. 9) which has a central QZOOVG4C8. 'This block is somounted that in 'thenormal position of adjustment the projecti'on15 ofthe plate 11 travels-down theside 49 of the block 41?. In'the abnormalpositionof adjustment the pro ection l5 passes down the'groove 48:,while in the position for adding justification to characters ittravelsdown'theside 50 of the block 47. When the parts are in initialposition the projection '15 can pass between the to'pofthe block 4;? andthe underside of the cover plate lG'permitting adjustment of the plate11. In any other position adjustment of the plate 11 is prevented.

In order to insurethat the plate 13 will not tilt particularly when itis operated bv a stop bar 6*engagi'ng at or neurone or its ends.two'leve'rs 51 and 52 pivoted at 53, 53 to 'thefront plate of the frame7 and have; their arms 54;. 54" nivotallvconn cted with a bar 55whichrests under the oven turned upper edge of the plate 13. while theother arms 56,6601? the levers 51 and are coupled together by a bar 57.A ension spring 58 has one of its ends'connec'ted to the arm 54 of thelever 51 and its opposite end to the arm56 of the lever 52so that whenthe bar 55 is pros'seddown. by descent oi. the plate 13 and'the levers5i and52 turned on their pivots. the spring is e:-;- tended; when thepressure of the bars 6 on the'plate'l3 is releasedthe spring 58 will mFor this iurpose there is provided, for co-operation with the rack 60, aspring controlled pawl 6i pivotally carried on a lever 62 tulcrumed toastationary support at and coupled by a link 64 to a lever 65 lulcrumedat 6 6. On the member 16 is an adjustable projection or look 67connected with the member 16 by a neck portion 68 passing through asuitable channel in the side of the frame 7. This block 67 projects intothe path. of the lever 65 so that each time the member 16 descends thepawl 61 is operated to move the rack up ward the extent oi? one tooth.

in operation, assuming normal conditions of a four unit basic value forthe space signal, the space key will be adjusted as shown in dottedlines in Fig. 11, and the slide 11 will be adjusted as shown in Fig. 2.It now a character key 1s struck it will produce its signal in the usuallashion. It the space key 25 is struck it'will operate key' bar 32 tocause operation or the bi punch to produce the transfer component of thespace signal and also the six unit punch which punch will in the usualmanner throw up the six unit stop. The operation oi? the t5 punch willmove the parts 16, 12 and 11 downwardly, the projection 14- on thelatter engaging with stop bar 18 to operate the four unit stop. Theoperation of the six unit step will have no eil'ect because it is behindthe four unit stop or further away from the zero position of the unitrack. F or what is herein called the abnormal condition in which thebase value of the space signal is to be seven units, the space key 25 isadjusted as in full lines in 11, and the member 11 is adjusted to theposition shown in Fig. l. llhese adjustments will have no ell ect uponthe operation 01 character or justification keys, but when the space key25 is depressed it will operate key bar 3-3 which will cause theoperation of the S punch producing the transter component oi? the spacesignal and the nine unit punch to produce the dimension component of thespace signal. The nine unit punch will operate in the usual. fashion tothrow up the nine unit stop. The S punch will operate the parts 16, 12and 11 depressing them to the-position shown in Fig. 1-, in whichposition the projection of the member 11 has operated the stop bar 22and the latter has thrown up the seven unit stop.

Under either condition, the parts 16, 12 and 11 and the operated stopbararo returned to initial position, when the space key is released, bythe springs 19 or It will. be seen that in the normal setting the casterwill receive a signal resulting in placing the matrix case in the sixunit position, although the ellective stop cit-the units measuringmechanism will be the four unit stop. In the abnormal adjustment thematrix case will be positioned in the nine unit position but the measureon the keyboard will be seven units.

When it is desired to add justilication to types or characters, theslide 11 is mo ed which position it is connected by the heel: 34 withthe slidingplate 13. When a character key is struck its signal will berecorded in the usual fashion. The punch for recording the dimensioningcomponent of that signal will not only throw up the stop n'leasuring thevalue of that signal, but will also by the engagement of itssheulder 40with the slide member 13, depress the latter thus causing the hook. 3-lto pull downwardly the slide member 11 and its elated parts 12 and 16 asshown in '1 5 and (F. The part 16 by engaging the walls of its socket 17with the lever 3 conne ted with the S punch will cause the oper tion ofthe latter so that the combined produced is of three components, thepositionmg component, the dimensioningcoin-- to the position shown in liggs. 5 and '(J', in i ter acting upon the lever 65 and its associatedelements will cause the space pointer 59 to move up one space, theactionso tar as the pointer 59 is concerned being the same as when,under any condition of adjustme "t the space key is struck. Sincetheaddition of the transfer component to type signals dec-reases the valueof the signal by two units it is necessary to make good this dd ficiencythrough the medium ofthe justification signals, so that the operatorhaving read the justification indicator must add two 'gether with aplurality o1. units admeasuring I devices, and in combination therewitha manually controlled I coupling mechanism movable into positions toconnectthe transter component signalproducmg devicewith one or the otherof selected units admeasuring; devices to operate the latter.
